Abstract

The invention relates to a reading lamp for sick-room beds. The lamp housing, which is fixed in the direction of emission, can be displaced in the longitudinal direction of the bed by means of a telescopic support arm. Such a reading lamp provides the user lying in bed with the possibility of displacing the lamp in the longitudinal direction of the bed. There is no change during this action in the conditions of glare with respect to the neighbouring bed either laterally or in the longitudinal direction.

"Reading light for hospital beds"

The invention relates to a reading lamp for hospital beds, the lamp housing of which can be displaced on a support arm fixed to the wall is.

Reading lights with articulated arms are known, in particular in connection with installation channels for hospital rooms can be set up spatially opposite the patient. One such reading lamp with an articulated arm is one in each case Assigned to hospital bed.

However, there is a requirement to assign a reading lamp that is sufficiently shielded from the neighboring area and that enables reading in any normal position. The illuminance at a standardized measuring point should be about 200 lux and the luminance of the reading lamp in the field of vision of neighboring or opposing patients should be at most 1000 cd / m ² .

For this reason, they are assigned to the hospital room wall or an installation duct arranged there Reading lights fixed to the bedside with a fixed direction of radiation. With appropriate anti-glare devices adequate shielding from the neighboring bed is achieved. These reading lights are equipped with elongated fluorescent lamps that ensure the required illuminance at the measuring point.

The previously customary fluorescent lamps are being used to an increasing extent replaced by the new generation of lamps with a smaller diameter, whose energy consumption is lower. However When using these lamps, there is a somewhat less favorable illuminance distribution over the length of the lamp. It It also shows in practice that the measuring point specified in the standard does not always match the reading plane of the one resting in bed Patients agrees, so that in both cases, under certain circumstances, the illuminance is insufficient.

The object of the invention is now to provide a. Reading light of the type mentioned to propose, while maintaining the glare-free against neighboring beds to a changed reading level in the sick bed can be set up.

The inventive problem is solved by a reading lamp type mentioned at the beginning, which is characterized by a lamp housing fixed in its direction of emission, which by means of a telescopic support arm in the longitudinal direction of the bed is movable.

With such a reading light, the user resting in bed has the option of fixing the light in the direction of radiation Move lamp in the longitudinal direction of the bed, so that the glare conditions cannot be changed either laterally or lengthways compared to the neighboring bed. Patients in neighboring Beds are therefore not bothered by moving the reading light.

According to a preferred embodiment of the invention, the support arm is arranged in a fastening housing and from it Pull-out front. This mounting housing can

formally adapted under one channel for another Be placed under the hospital room installation, with the lamp housing protruding upwards in relation to the support arm the height of the channel and its front is formally adapted. When the support arm is pushed in therefore, the luminaire housing rests on the installation duct or on the mounting housing of the support arm.

The invention also includes the proposal to provide a laterally angled support arm, whose to the longitudinal direction of the bed vertical leg is also telescopic. Such an angled support arm enables even after the installation has been set up, the adaptation to the position of the Sick bed to the lamp, as such a lamp can also be moved parallel to the wall in a certain area.

So that the leg parallel to the wall of the angled support arm does not necessarily have to play between the individual telescope parts falls obliquely downward in the extended state, it proves to be useful to the End of this support arm leg to provide sliding pieces that are attached to the sub-assembly under an installation channel in slide rails be held in the canal.

The invention is based on the illustrated exemplary embodiments explained in more detail below. Show it:

Figure 1 is a cross-sectional view of a reading lamp according to the invention, which under is placed under an installation duct in the pushed-in position of the support arm,

FIG. 2 is a side view for illustration in FIG

Figure 1 with extended support arm,

Figure 3 is a plan view of two on one

Reading lights arranged in an installation duct with angled support arm

and

Figure 4 shows a detailed representation of a below the

Installation channel below the support arm.

Reference is first made to FIGS. 1 and 2. Under an installation duct 1 fastened to a wall 4 a fastening housing 31 is placed below it, from which A telescopically extendable support arm 3 protrudes from the front. On this telescopic arm 3 is a lamp housing 2 attached with a fixed direction of radiation. The reflector is in the actual radiator 21 indicated. The housing section 23 is formally the pre

adapted to the front of the channel 1. As Figure 1 shows, d ^; 'This housing section 23 is pushed up to the sloping area of the channel.

In practice, the extendable length of the support arm 3 is approximately between 250 - 350 mm.

In the embodiment according to ^{FIGS. 3 and 4, the lamp housing 2 1 is} displaceable on a laterally angled support arm 3 '. The leg 3'a, which is parallel to the wall and can also be pulled out like a telescope, is fastened on or under a channel 1, which in turn is fastened to a wall 4. In this way, the lamp 2 'can be set up towards the center of the hospital bed indicated by the number 5. The leg 3'b of the support arm 3 'running in the longitudinal direction in turn enables the lamp 2 to be displaced parallel to the plane of the beds 5.

From Figure 4, the possibility of attaching a support arm 3 * can be seen on the installation duct 1. At the end of the support arm leg 3'a, which is parallel to the wall, a slider 12 is provided, which in slide rails 13, 13 'ata of the lower wall near Corner of the channel 1 is displaceable.
